We visited a handful of the best installations, which ranged from Open Desk’s inquiry into the future of office furniture to Alison Brooks’s and Arup’s investigation into the potential of new architectural materials and engineering, and the first-ever London Design Biennale–an exploration of what utopian design means today.
